1. Operating characteristics of self-adjusting oil pressure dampers
In a conventional vane damper. the damping strength (damping constant) does not change regardless of the load torque used. Because
of this, its working speed is slower when the load torque is small, and faster when the load torque is large. However, because the self
adjusting FYN-51 series is designed to self-adjust the damping force (damping constant) according to the applied load. the working speed
fluctuates less compared to conventional dampers when the applied load is altered. The acceptable range or torque is 5 ~1 0N·m. Please
select your damper by referring to the motion-time graph below.

As the level of self-adjustment may vary
depending on the range of the working angle
of the actual work, please verify under actual
working conditions before you select your
damper.
